Mitutoyo 614194-531 Square Steel Gage Block 0.4 in Grade 0

Product Description

The MITUTOYO 614194-531 is a square steel gage block measuring 0.4 inches, manufactured to Grade 0 accuracy standards per ASME specifications. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set up inspection fixtures, and verify dimensional accuracy in machining and metrology environments. This block ships with a Certificate of Inspection, confirming it has been measured and documented to meet Grade 0 tolerance requirements. Grade 0 represents a high level of dimensional accuracy suitable for lab-grade calibration and precision inspection work. The steel construction provides durability and resistance to wear under repeated wringing and handling by quality control technicians and metrologists.

This gage block is used in metrology labs, machine shops, and quality control departments wherever traceable dimensional references are required. Typical applications include calibrating micrometers, calipers, and height gages, as well as establishing precise setups on surface plates. The 0.4-inch size fills a common increment in a gage block set or serves as a standalone reference block for specific measurement tasks. Both production floor inspection and laboratory-grade calibration workflows are supported at this accuracy grade.

Key Features

• Grade 0 accuracy per ASME standards for high-precision dimensional reference
• Steel construction for long service life and dimensional stability
• 0.4-inch nominal size with five-decimal precision (0.40000 inches)
• Includes Certificate of Inspection for traceability documentation
• Square form factor compatible with standard gage block accessories and holders

Compatibility

Designed as an OEM-grade precision reference block suitable for use with standard gage block accessories, holders, and wringing fixtures compatible with square-style steel gage blocks.

Installation Notes

Gage blocks are handled and set up by metrologists and quality control technicians, not installed in the traditional trade sense. Store blocks in their protective case when not in use to prevent corrosion and damage to lapped surfaces. When wringing blocks together, apply a light coat of calibration-grade oil and use proper wringing technique to avoid surface damage. Clean surfaces thoroughly before and after each use to maintain accuracy and prevent rust on steel blocks.
